Since I have SEEMED to be awol of late... Answered

this is a short SHORT bit of what I've been planning, and doing of late.

The VERY short video shows my young student repeating the "experiment" we've just executed together, but now for the rest of her family.

It is a demonstration that #1:  milk has fat/oils in it, and #2 that detergent breaks these up, and #3: that it does so rather rapidly.

By the time I got the camera ready, she'd already poured a little milk into a saucer, and dropped some different colors of food coloring on the surface tension of the milk.

The video only shows the reaction once she drops the detergent onto the coloring (and if you have the volume up, you can hear her little sister in the background go OOOOOO :-) .

My apologies for the very VERY poor quality of the shot,  next time I will prepare ahead of time, with my tripod, for any filming I need to do.

Cool experiment! I want to try it out but I am running out of milk, if I don't have milk for my coffee tomorrow my day is ruined.

I saw something like that before with multiple colours and the results were gorgeous. Is there any way to have the colours set permanently, and use it to decorate ceramics or something like that.

You only need a thin layer of it in a saucer. Put the drops of food coloring carefully on top, include different colors and if you make the neighboring colors "clash" between light and darker colors, it will be even more interesting. Sometimes you can get them to dance all around with a couple of drops of detergent placed some distance apart from one another. Whole milk works best (I bought a half pint of it especially for this experiment). Have fun :-)

OH and then post what you think is happening....I am going to go through the steps with Cindy to get her to think about it, and try to figure it out.
